They have 8 1/4 x 10 1/4. If any one can find a price better than 36 for 2.97 let me know. The last time I got a stock pile of different sized bags from here, they had a $1.97 flat rate shipping special. Otherwise, it's 100 for free shipping which IS a bit steep. However, they do have great prices on other items as well. Hope this helps!
